There is a 50/50 chance of being a boy or a girl for both children. The genders of both children are mutually independent (mathematically speaking, this means that the outcome of one random event does not effect the outcome of another event; in this case, the gender of one child does not effect the gender of another.)

Probability of having at least one boy is 78.

50. e) Since births of children are independent of each other, the first child’s sex has no bearing on the other’s. Since about half of the births are male, the probability of the second child being a boy is . 50.

For every 100 girls born, around 105 boys are born . So, in general you’re slightly more likely to have a boy than a girl. In years when the weather is warmer, more boys tend to be born . Some research also shows that more boys might be born in warmer climates .

A child’s gender (male or female) is determined by the chromosome that the male parent contributes. Females have XX sex chromosomes. Males have XY sex chromosomes. A male infant results if the male contributes his Y chromosome while a female infant results if he contributes his X chromosome.

The short answer to this question is no, not through sexual intercourse. Two cisgender women (meaning assigned female at birth) in a relationship cannot become pregnant without some form of assisted reproductive technology (ART). The reasoning goes back to basic biology and how an embryo is formed.

Because becoming pregnant is likely something that you want to carefully plan, it’s important to remember that anytime sperm comes in contact with the vaginal canal, it’s possible to become pregnant ⁠— even if most of the semen comes out or never goes in!

A lithopedion – also spelled lithopaedion or lithopædion – (Ancient Greek: λίθος = stone; Ancient Greek: παιδίον = small child, infant), or stone baby, is a rare phenomenon which occurs most commonly when a fetus dies during an abdominal pregnancy, is too large to be reabsorbed by the body, and calcifies on the outside …

How does teenage pregnancy affect teen mothers? Teens are at a higher risk for pregnancy-related high blood pressure (preeclampsia) and its complications than average age mothers. Risks for the baby include premature birth and low birth weight. Preeclampsia can also harm the kidneys or even be fatal for mother or baby.

It’s perfectly normal for boys and girls to start liking each other during the preteen years. It’s very new, so it might feel awkward or strange. It’s also fine if kids feel too young to get involved in this lovey-dovey stuff. The good news is that almost all kids think girls and boys can be friends.

Bottom line: Men generally see a decrease in fertility beginning at 35, and the decline progresses from there. The age men are most fertile may be between 30 and 35, but we haven’t yet determined a specific window of peak fertility.

“It’s exceptionally rare for patients to get pregnant naturally at 50 or over 45. They make history,” said Dr. David Keefe, an obstetrician-gynecologist and fertility researcher at New York University. In part that’s because around age 50, many women are entering menopause, after which egg harvesting isn’t possible.

By ages 46 to 50, the success rate was down to 32 percent. And men over age 51 were able to facilitate pregnancy just 30 percent of the time. “This drop-off will also be related to the maternal age and this decline in pregnancy rate becomes quite dramatic over 35 years for a woman,” Morris told Healthline.

Due to advances in technology surrounding fertility, pregnancy, and delivery, it’s possible to safely have a baby at age 40. However, any pregnancy after age 40 is considered high risk.

According to a 2016 report from the C.D.C., one in vitro fertilization cycle has a 36 percent chance of successfully impregnating a woman under 35, whereas it has about a 22 percent chance for women between 38 and 40, about a 13 percent chance for those 41 or 42, and about a 6 percent chance for women over 42.

A new study shows that the age of the male partner can have just as big an impact on fertility and the time it takes to successfully conceive a child as the age of the mother. Researchers found it takes up to five times as long for a man over 45 to get a woman pregnant than if he was under 25.

The U.S. National Birth Defects Prevention Study found that women greater than age 40 are at increased risk of having babies with multiple types of heart defects, genital abnormalities, skull deformities, and esophageal malformations.

“About 50% of women who try to conceive naturally in their early to mid 40s will achieve a pregnancy.
